What the Arabs have not been able to accomplish in 63 years, Israel may do it for them by its own actions - destroy itself.
If Israel attacks Iran, it may destroy some or all of Iran's nuclear facilities, but one thing is certain, Iran will throw everything at Israel that it has in its arsenal and it will have a good reason to do so and possibly also have the backing of majority nations.
Such an Israeli action will unite the entire Iranian nation behind Mullahs (whom they despise and detest) thus strengthening their hands. Those mad Mullahs would love to wreak havoc on Israel. Imagine 500 pound bombs landing on Tel Aviv and other Israeli cities demolishing everything in their way.
If Iran is attacked, the Iranian backed Hezbollah in Lebanon will also not sit idly by. They have even bigger and better rockets now compared to the ones that created havoc in Israeli skies in last Israel-Lebanon war.
I hope the Israelis will be sensible enough to think through the consequences of such an action and calculate cost of starting a mindless and destructive war. There may be a small group of extremists in Israel and some idiotic politicians and rabid Evangelical preachers in the US, who want them to do this, but is this really what the majority of Israelis want? I think not.
Instead of starting a suicidal war, Israel will be well advised to urgently start negotiations with Palestinians for a permanent peace, so that Israelis and Palestinians can exist side by side as two friendly and equal neighbors.
